Definitions

  • the invention relates to a method and a device according to the preamble of claims 1 and 7.
  • Modern spinning machines are usually assigned to transport devices which receive or temporarily store the yarn packages produced on these machines and remove them for packaging.
  • bobbins of thread are packed on pallets for shipping so that the bobbins are arranged on the pallet with a standing bobbin axis in order to protect the yarn layers.
  • the bobbins that come from their winding point with the horizontal winding axis must be brought into this palletizing position for palletization and transported from the machine to the pallet without touching the yarn layers.
  • a six-axis handling machine for automatic bobbin take-off on a rotor spinning machine which, with an electronically controlled gripper, recognizes and grips the bobbin and its orientation at the end of an assembly line ejecting the bobbin from a rotor spinning machine and transfers it electronically to a bobbin transport carriage (VDI news no. 44 ; 30.0kt.87 page 36 ff.)
  • This device is extremely expensive and complex due to the use of a robot controlled via six axes.
  • the sleeve protruding from the end face of the coil lies between the tapes which carry the end face of the coil.
  • These parallel belts transport the tilted bobbins to the desired position under a gripping device so that the bobbins can be removed to place them on a pallet.
  • This arrangement is very space-consuming and relatively complicated. Electronically controlled search and positioning devices are required so that the take-off device on each spinning machine can adjust itself to the corresponding bobbin format or associated hole pattern of the intermediate layers.
  • a device is known from DE-A-39 12 683 which consists of a tilting element 25 and an attached positioning belt conveyor 26 and a centering device 35.
  • This tilting element serves to align the axis of the coil vertically by turning it 90 degrees. It works over a horizontal positioning belt conveyor, which is designed so that it transfers the spools after their tilting movement to this positioning belt conveyor 26, which in turn feeds the spool to a centering device, which ensures the exact positioning of each spool, so that a gripper 47 grips the spool and one Loading level can feed.
  • this device three devices, namely tilting device, positioning and centering device, are provided in order to tilt a coil and bring it into a position which is provided for a gripper receptacle.
  • This device is relatively complicated and expensive.
  • the coil is centered on its circumference, there is a risk that the turns will be damaged.
  • DE-A-37 42 220 shows a generic device and a method in which a coil is tilted and positioned. However, the coil axis is not fixed, so that there is a risk that the coil will spring back to the stop on impact and will not assume the intended position.
  • the object of the present invention is to avoid the disadvantages of the prior art and to provide a method and a device for bringing the spools delivered by a conveyor belt into a defined position in a simple, safe and space-saving manner, from which they are moved by a Gripping device can be removed.
  • the invention makes it particularly advantageous to bring coils into the intended position regardless of their coil diameter and taper.
  • the difficulty of having to handle different diameters of the bobbins delivered by the spinning machine does not arise at all with this procedure, since the coils are positioned over the coil sleeve and thus a clear positioning of the coil center is always achieved in a very simple manner.
  • FIG. 1 shows an embodiment of the device according to the invention in a side view before a coil 5 tilts in the situation shortly before the coil 5 leaves a conveyor belt 6 and arrives on a support plate 9 of a tilting device 1.
  • the support plate 9 can be provided with a slight increase on the side in order to pre-center the coil 5 to such an extent that its coil sleeve 51 is securely inserted into a positioning device 2.
  • the tilting device 1 is shown here in a version attached to the end of a conveyor.
  • This conveyor belt contains the conveyor belt 6 onto which packages of different sizes are placed by a device (not shown) and are conveyed from the conveyor belt 6 to the end of the conveyor belt (to the right in this example) in order to be tilted and positioned by the tilting device 1, so that the coil (in the position as shown in Figure 3) can be removed from a handling device coming from above.
  • Two different coil sizes are shown here, namely a small coil with the coil axis "A” and a large coil with the coil axis "B”.
  • the coils are transported by the conveyor belt 6 in the direction "F" (direction arrow "F") against a plate 3 of the tilting device.
  • the plate 3 of the tilting device 1 is rotatably mounted about an essentially horizontal axis of rotation 10.
  • the support plate 9 is approximately attached at a right angle to the plate 3 at the height of the conveyor belt 6 and continues in a lever arm 31, in the bearing point 91 of which a piston rod 411 of a piston 41 is articulated.
  • the piston 41 is the displaceable part of a pneumatic cylinder 4, which is articulated with its cylinder end in a fixed bearing point 40.
  • the arrangement is now advantageously coordinated so that the piston 41, when it moves the piston rod 411 down in the cylinder 4, tilts the plate 3 clockwise about the axis 10 (in this figure), so that the plate 3 is essentially horizontal comes to rest by coming to rest against an adjustable stop 102, which is fixed at the end of the conveyor belt 20.
  • the position of the tilted plate 3 shown in FIG. 3 is then present.
  • the piston rod 411 of the pneumatic cylinder 4 is articulated.
  • a stop 14 is now arranged in the pivotable plate 3 and can be moved in the guide 15.
  • This slidable stop 14 has an axis 133 on which a coupling 13 is articulated.
  • the stop 14 is freely displaceable between a leading edge 141 and the fixed stop 16, which is arranged in the plate 3.
  • the coupling 13 is equipped in its end opposite the articulation point 91 with an elongated hole 131 through which a pin 71 fixed in the holder 7 passes.
  • a spring 17 is also attached to the coupling 13, which, if it can carry out a movement in the region of the elongated hole 131 due to the tilting movement of the plate 3, the coupling 13 in the direction of Fastening point 72 of the spring 17, which is attached to the bracket 7, pulls.
  • An attachment 11 is now attached to the displaceable stop 14, which is arranged displaceably with respect to the displaceable stop 14 and can be pressed away from the stop 14 by spring elements 111.
  • the attachment 11 can move resiliently against the stop 14 if it encounters an obstacle.
  • the coil sleeve 51 projecting over the coil surface that rests on the tilting device 1 is gripped and positioned by the positioning device 2.
  • the positioning takes place independently of the present coil diameter, since it is directed exclusively towards the coil sleeve 51.
  • the removal of the coil 5 by a gripper is thus much easier since the coil center is always in the same position with the same coil sleeve diameters.
  • a bracket 32 is rotatably mounted about an axis of rotation 321. This bracket is pressed by a spiral spring 3211, which is supported in the plate 3 in the direction of the conveyor belt 20 and held on a holding edge 331 of the switch 33.
  • the switch 33 mounted on the plate 3 is designed here as an inductive switch, the switching pulse being triggered depending on whether or not there is a metallic object in front of the switch. In the example, this metallic object is given by the cross bar 322.
  • the bracket 32 is designed as a double bracket, which essentially has the shape of an inverted "U".
  • the crossbar 322 of the bracket (FIG. 4) is in the state in which no coil presses against the plate 3 in the area of the switch 33 in which the switch 33 is influenced.
  • the removal of the crossbar 322 of the bracket 32 from this area has the consequence that the switch 33, which is designed as an induction switch, transmits a switching pulse to a controller 18, not shown, of the device in order to initiate the tilting process.
  • the process now proceeds as follows:
  • the conveyor belt 6 moves in the direction of the arrow "F" and carries a spool 5 to the tilting device 1.
  • the spool 5 leaves the conveyor belt 6 and reaches the support plate 9, pushed by the action of the conveyor belt 6 and pushes the bracket 33 in the direction of the plate 3, so that this bracket 33 rotates about the axis 321 and the coil 5 evades.
  • the transverse part 322 of the bracket 32 is moved out of the effective range of the switch 33 and thus triggers the switching off of the drive of the conveyor belt 6.
  • the switch 33 controls a solenoid valve, not shown, which acts on the pneumatic cylinder 4 in such a way that the piston rod 411 moves into the cylinder of the pneumatic cylinder 4.
  • the coupling 13 moves now by gravity and by supporting the spring 17, which is fixed in the attachment point 72 to the bracket 7 and on the other hand engages the slot-side end of the coupling 13, such that one pivot point 133 of the coupling is rotated about the axis of rotation 10 and the other end of the Coupling 13 is simultaneously rotated and displaced by the pin 71 "running" in the elongated hole 131 until the "upper" end of the elongated hole is reached by the pin 71.
  • the coupling 13 is only rotated about the fixed pin 91, which causes the movable stop 14 articulated on the coupling 13, which is displaceably arranged in the plate 3, to move in the direction of the fixed stop 16 and the end of the coil sleeve 51 of the coil projecting into the path of the movable stop 14 and thus pushing the coil 5 itself in the direction of the stop 16.
  • the device is set so that when the rotation of the plate 3 about the axis of rotation 10 is completed - that is, the position in which the plate 3 rests against the stop 102 - the coil sleeve 51 of the coil 5 is displaced exactly to the extent that it shaped stop 16 and on the V-shaped attachment of the movable stop 14 is tight and is thus defined position.
  • FIG. 3 shows the position already described above, in which the coil is positioned and is ready for removal by a gripper from a position provided for the gripper holder.
  • the axes A and B of the small and large coils, which are superimposed before tipping, are now in the same place.
  • the coil 5 is pushed away by the displacement of the stop 14 from the support plate 9 in the direction of the fixed stop 16.
  • Figure 4 shows an embodiment of the device according to the invention, which is attached to a double conveyor belt, wherein advantageously only one pneumatic cylinder 4 is necessary for two plates 3.
  • the device is not shown completely for reasons of space. Imagine them mirrored on the axis of symmetry "S".
  • the two plates 3 are connected to a connecting plate 19, the articulation point 91 of the lever arm 31 of the plate 3 being moved out of the plate 3, exactly in the middle between the two plates 3. This ensures that only one cylinder 4 is necessary specifically for the plate 3 to be tilted, which is currently in use.
  • This multiple arrangement of plates 3 on a tilting device 1 can of course also be used directly on the spool conveyor of a spool producing machine.
  • a pneumatic cylinder instead of a pneumatic cylinder, a worm drive or gear / rack drive can also be used at this point.
  • the switching and control device via the bracket 32 and the switch 33 can also be replaced by conventional switches and / or sensors. It is also conceivable that the bracket 32 directly actuates a pneumatic valve for controlling the pneumatic cylinder 4.
  • the impulse to trigger the tipping process can also be initiated by an indirect control which, for example, determines the position of the spool delivered on the conveyor belt 6 at the point relevant for tipping.
  • the coupling 13 can also be designed without an elongated hole, in that instead of the elongated hole at the end of the coupling, only one hole is provided through which the pin 71 is inserted. However, this means that it is no longer possible to tilt all the different coil sizes delivered by the conveyor belt between the stops in the "open" position safely and precisely. The processable bandwidth of the different coil diameters would be much smaller.
  • FIG. 4 also shows the arrangement of the stop 11, which is elastically connected to the displaceable stop 14 via pins 141 and spring elements 111.
  • the attachment 11 and the stop 14 run, for example, in tongue and groove or other form-fitting guides 15. It is shown in FIG. 4 also clearly shows the area in which the coil diameters lie which can be processed without the tilting device having any special or complex devices.
  • the processable range of coil diameters is between d A and d B.
  • the invention is not limited to the embodiment shown. It is also possible, for example, to arrange the device according to the invention instead of stationary on conveyor belts or the like, to provide it in mobile palletizing or packaging devices which move up to the conveyor belt to be unloaded and carry out the unloading process.
